A relay kit our part number ccfkrl will include everything you need to properly wire up your electric cooling fans with the exception of additional wiring needed to complete all of the circuits. In the painless performance electric fan relay kit we got from speedway motors a circuit breaker is supplied if you wanted to safely get power directly from the battery.

This will be your new ground switched output. For this set up we also used two of the speedway universal electric radiator cooling fan part number 910158 which comes in a 10 12 14 or 16 inch diameter. If the fan is not turning in the right direction air will be blown away from the radiator and will not help to cool the radiator. Ground switched device using a simple spst relay.
